You didn't specify your category of performance- so I am guessing engine.
Transmission performance of adding 3.73 gears will do alot- but will require a tune calibration to correct speedo for your dash and the computer. If you have a 7.5 axle- check for posi-trac rear end. If it is not- add a posi differential. No more single wheel burnouts.
1. Cold air kit- make sure it is an actual kit that draws in cold air- not hot air from radiator.
2. MAC headers
3. supercharger from Kenne Bell- check out his web site and go for the kit.
